The Sunrun story

What drives the business

• Sunrun's core business is residential energy subscriptions, with homeowners typically signing leases or power purchase agreements lasting 20 or 25 years and Sunrun monitoring, maintaining and insuring the systems during the contract.
• Customer payments and tax benefits support tax equity, non-recourse debt and project equity financing for upfront installation costs and growth, a model supported by Sunrun's placement of a $267 million securitization in August 2026.
• Direct operations and partner channels bring in customers, while a transaction begun in the quarter to September 2025 transfers certain newly originated systems to a third party and was the primary reason energy systems and product sales revenue rose 193% to $326.3 million in the quarter to June 2026.
• The shift toward batteries adds backup power and energy management to the subscription offering, with Storage Attachment Rate rising to 74% in the quarter to June 2026 from 70% in the prior-year period.
• Sunrun, Renew Home and Tesla announced a nonbinding letter of intent in June 2026 to deliver more than 16 gigawatts of flexible capacity to hyperscalers and utilities, and Sunrun launched a distributed AI data center pilot in July 2026.

What the price assumes

At $7.67, the reverse DCF cannot measure an implied growth rate because free cash flow of -$202 million over the last twelve months provides no positive cash flow base, leaving the valuation dependent on future profits.

Revenue grew 63.2% over the last twelve months, compared with an annual pace of 8.4% over the last three years, but that growth has not produced positive free cash flow.

The free cash flow yield of -10.9% falls short of TenQ's check requiring a yield above 3%, despite a price to earnings ratio of 5.0x.

What could change the story

• Reduced affiliate channel volumes, a delayed expansion of direct sales activities and higher capital costs prompted the reduced outlook for 2026, making both customer acquisition and financing costs central to the recovery in subscriber economics.
• Total debt is $15.2 billion, although $14.5 billion is non-recourse and secured by customer payments rather than Sunrun itself, with $628 million classified as recourse debt.
• TenQ's interest coverage check is 0.12 against a required 5.00, underscoring the gap between earnings and financing costs.
• Sunrun's non-GAAP Cash Generation measure incorporates capital raised from non-recourse sources, so positive Cash Generation does not establish that operations fund installations without outside financing.
• Shares increased 20.7% over the last three years, and stock-based pay totaled $105 million over the last twelve months, adding dilution alongside the funding demands of the business.

What to watch next

• For full-year 2026, Sunrun expects Aggregate Subscriber Value of $4.6 billion to $4.9 billion, reduced from $4.8 billion to $5.2 billion.
• Its Cash Generation outlook for 2026 is $200 million to $375 million, excluding potential equipment safe harbor investments, compared with prior guidance of $250 million to $450 million.
• The next releases will show whether direct sales productivity and affiliate volumes improve, with Subscriber Additions, Net Subscriber Value per addition and operating cash flow testing whether record battery attachment translates into stronger economics.
